acceptance of the unconformity-related nature of the Nicholson Bay Au-PGE mineralization raises speculation about the exploration potential of other unconformities as those below the Martin Group" (Summary of Investigations-1988 Project 8832, Saskatchewan Geological Survey, pg.
The use of a computer for correlation exercises will give participants the ability to "hyper-correlate" to detect subtle unconformities and to quickly experiment with different datum choices as their interpretation progresses.
